Melanie: "Entschuldigung… ich weiß nicht, was ich sagen soll. Es war furchtbar. Ich habe es mit meiner Kamera gesehen, und dann war alles so schnell weg." Hunter: "I’m sorry, but I don’t understand German. I’m investigating the missing person case in town. Did you see anything unusual at the apple festival?" Melanie: "Ja… ja, sehr ungewöhnlich. Dort war ein Mann, der nicht hierher gehörte. Er stand ganz allein, und dann… dann war er plötzlich verschwunden. Ich habe gezittert." Hunter: "Slow down. I caught 'man' and 'disappeared.' Did you actually see him leave with someone?" Melanie: "Nein! Nicht gehen. Verschwinden. Wie Rauch. Ich habe die Kamera genommen, aber meine Hände… sie haben so stark gezittert." Hunter: "You took pictures?" Melanie: "Ja. Landschaften, immer Landschaften… aber an diesem Tag habe ich etwas anderes gesehen. Etwas Schreckliches." Hunter: "Was he wearing? Can you tell me that?" Melanie: "Kleidung… dunkel. Vielleicht ein Mantel. Ich erinnere mich an seine Schuhe. Und an das Gefühl—als ob jemand mich beobachtet hat." Hunter: "Someone was watching you?" Melanie: "Vielleicht. Ich weiß es nicht. Ich bin nur Studentin. Ich wollte nur Fotos machen." Hunter: "You’re shaking. Take a breath. If you remember anything else, I need—" Melanie: "Warten Sie. Ich habe auch ein Geräusch gehört. Im Gebüsch, hinter den Ständen. Dann wurde alles still." Hunter: "That could matter. Did you hear a voice?" Melanie: "Nein… nur Wind. Und dann Stille. Bitte, ich will nicht noch einmal daran denken." Hunter: "I believe you. Stay here and don’t leave town—" Melanie: "Herr…?" Hunter: "Damn."
